Follow this guide to replace the battery on a Google Pixel 4a 5G.

For your safety, discharge your battery below 25% before disassembling your phone. This reduces the risk of a dangerous thermal event if the battery is accidentally damaged during the repair. If your battery is swollen, take appropriate precautions.

The unreinforced display panel of the Pixel 4a 5G is fragile. Pay special attention to the warnings in the opening procedure if you are reusing the screen.

  1. Insert a SIM eject tool, bit, or straightened paper clip into the SIM tray hole. Press directly into the hole to eject the SIM card tray. Remove the SIM card tray.
    • Insert a SIM eject tool, bit, or straightened paper clip into the SIM tray hole.

    • Press directly into the hole to eject the SIM card tray.

    • Remove the SIM card tray.

  2. You will need to pry the screen up to remove it from the phone. Read the following notes carefully before proceeding. Take note of the two seams on the edge of your phone: Screen seam: This seam separates the screen from the rest of the phone. This is where you have to pry.
    • You will need to pry the screen up to remove it from the phone. Read the following notes carefully before proceeding.

    • Take note of the two seams on the edge of your phone:

    • Screen seam: This seam separates the screen from the rest of the phone. This is where you have to pry.

    • Frame seam: This is where the plastic frame meets the back cover. It is held in place by screws. Do not pry at this seam.

    • Before you begin, note the following areas on the screen:

    • Screen flex cable: Do not insert the opening pick deeper than instructed or you risk damaging this cable.

    • Adhesive perimeter: Prying beyond this narrow perimeter without angling the pick will damage the OLED panel.

  3. Apply a heated iOpener to the right edge of the display for one minute to soften the adhesive.
    • Apply a heated iOpener to the right edge of the display for one minute to soften the adhesive.

    • A hair dryer, heat gun, or hot plate may also be used, but be careful not to overheat the phone—the display and internal battery are both susceptible to heat damage.

  4. If your display is badly cracked, covering it with a layer of clear packing tape may allow the suction cup to adhere. Alternatively, very strong tape may be used instead of the suction cup. If all else fails, you can superglue the suction cup to the broken screen. Place a suction cup as close to the right edge of the screen as possible. Lift the suction cup with a strong steady force.

    • Place a suction cup as close to the right edge of the screen as possible.

    • Lift the suction cup with a strong steady force.

    • Insert the tip of an opening pick into the screen seam no more than 1 mm.

  5. This step shows how to insert your pick without damaging the OLED panel. Do this before slicing the adhesive. With the pick 1 mm into the gap, pivot the pick upwards to a steep angle. At a steep angle, carefully push the pick into the gap about 1/4 inch (6 mm). The pick should slide in below the OLED panel.

    • At a steep angle, carefully push the pick into the gap about 1/4 inch (6 mm). The pick should slide in below the OLED panel.

    • Stop if you feel the point of the pick hitting a ridge. The pick may be pressing against the edge of the OLED panel. Angle the pick and try again.

  6. Slide the pick along the right edge of the screen to cut the adhesive. Do not insert the pick more than 1/4 inch (6 mm) or you may damage the screen's flex cable. Leave the pick in the bottom-right corner to prevent the adhesive from re-sealing.
    • Slide the pick along the right edge of the screen to cut the adhesive.

    • Do not insert the pick more than 1/4 inch (6 mm) or you may damage the screen's flex cable.

    • Leave the pick in the bottom-right corner to prevent the adhesive from re-sealing.

  7. The screen adhesive is weak, so you should not need to re-apply heat. If the screen is hard to slice, apply heat to the difficult area for one minute and try again. Insert another opening pick into the right  edge of the phone at an angle where a gap has already formed to prevent damage to the OLED panel. Slide the opening pick around the top of the phone to cut the adhesive.

Hi Sam,

Do you know where to actually buy battery replacements for the 4a 5g? It doesn’t seem like it’s available just doing a Google search, and just wondering if you know something I don’t.

Thanks,

Sally

Hi Sally,

Not right now, unfortunately. It’s likely a matter of time before they are available, but it’s difficult to predict exactly when—especially with impacted global supply chains. Keep an eye on iFixit and eBay, and check with any repair shops if you haven’t already.

Best of luck,

Sam
